That assumes the user agent displays the filename to the user, not all
do. Links (for example) treats an image with no alt attribute as if it
had alt="", this is a great boon when faced with a page that uses a
hundred spacer.gif files, but not so when important content is hidden
in an image.

Can we really depend on specific error recovery features of particular
user agents? Especially when they are harmful in some circumstances?
Or do we expect end users to try to access a page in as many user
agents as possible until they find one which can compensate in a way
that is useful for that page?
